Sodium glucose linked transporter 2 (SGLT2) inhibition not only reduces morbidity and mortality in patients with diagnosed heart failure but also prevents the development of heart failure hospitalization in those at risk. While studies to date have focused on the role of SGLT2 inhibition in left ventricular failure, whether this drug class is ...

Failure Rate Prediction and Reliability Assessment of RV Reducer
2019 International Conference on Quality, Reliability, Risk, Maintenance, and Safety Engineering (QR2MSE), 2019Based on fuzzy mathematics thought, a methodology combining the expert evaluation and multilevel hierarchy analysis (EE-MHA) is proposed, meanwhile, the non-electronic product reliability data, NPRD) of non-key parts is used to predict the reliability of RV reducer in six-axis industrial robots. First, the proportion of every component of RV reducer in

RV Reducer Backlash Analysis Based on Robust Design
Applied Mechanics and Materials, 2011The RV reducer backlash is well controlled by means of robust design. Some factors influencing backlash are analyzed and divided into controllable factors and uncontrollable (noise) factors. The requirements for experimental factors are met for robust design. The experiment analysis is proposed by using orthogonal experiment and G.Taguchi robust design

Free Vibration and Sensitivity Analysis of RV Reducer
2017This work develops a dynamic model to investigate free vibration characteristics of RV reducer. The dynamic model considers key factors affecting vibration such as involute and cycloid gear mesh stiffness, crankshaft bending stiffness and bearing stiffness. For the model, equation of motion is derived.

Allopurinol reduces RV mass in patients with severe COPD
Right ventricle, 2018Background: Oxidative stress has been implicated in the development of pulmonary hypertension (PH) and right ventricular (RV) hypertrophy. It is well established that xanthine oxidoreductase can act as source of reactive oxygen species, which lead to oxidative stress.
